Patch returns undefined

[Saadi Sidali]

I was trying to make a service that tells the user how many elements got patched
the find method on the service returns an object but patch does not

The ui updates automatically and all that good stuff, even hooks work properly

but it would be nice if patch or other methods could return an object

[Marshall Thompson]

All methods should return an object. The only time it won't return the data should only be when the data being returned does not have an attribute that matches the "idField" configuration on the service.
